//! \ingroup OpenMayaFX
//! \brief Class for evaluating surfaces as triangles over time. 
/*!
    MDynSweptTriangle provides access to surfaces (Nurbs and Polys)
	defined as triangles.  It can only be accessed with the
	MFnDynSweptGeometryData class that is provided as an output
	from the geoConnector node.

    The class provides parametric time evaluation for a triangle.
    Time is in the range 0 to 1, where 1 represents the current frame and 0
    represents the previous frame. In this way you can get interpolated
    values of a triangle in motion.
